His happens to be swimming. Crazy Chris basically tells us to burn body fat you need to burn energy by playing sports and having fun!

This video shows you how to break a yardstick with atmospheric pressure. The instructor first lays a ruler halfway on and off of a table. He then covers half the ruler with newspaper. The instructor states that you can chop the ruler in half with your hand because the air holding down the paper will keep the ruler in place. The experiment does work correctly and he did break it in half perfectly. This instructor seems to have many similar videos on the subject.

Learn how to find latent finger prints on brass surfaces, such as fired cartridge cases. Called the Acidified Peroxide method, using only white distilled vinegar and hydrogen peroxide that you can find at your local drugstore, you can uncover fingerprints that is usually impossible to see using other methods. After mixing the vinegar and hydrogen peroxide the solution should start turning a greenish color around the brass object after 5 to 10 minutes. After you see the green color throw away...

This is a great video presentation of how Sodium Potassium Pump can maintain a voltage gradient across a cell. It also discusses various things like the differences between positive and negative charges and positive and less positive charges etc. The video tries to explain a lot of things happen within a cell when you fluctuate the voltage of sodium as well as positive and negative ions within a cell. You must watch it yourself to see the changes happen within a cell when you make some changes.

In this video the author show how to find the volume of a sphere. The formula for finding the volume of a sphere is 4/3 * Pi * r*r*r, where r is the radius of the sphere. Now to compute the volume of a sphere you have to note down the radius of the sphere and substitute it in the above formula along with the other substitutions. The author shows this with an example by taking a sphere of some radius and calculating its volume. To find out how to calculate the volume of a sphere watch this video...

This short video is about melting a styro cup without fire. It's magical. Anyone watching it would wonder what had happened to the Styrofoam cup which was dipped in Acetone, nothing but common nail polish remover. This is a short and cute video and watching this could be fun for kids. The fun element comes at the later part of the video. This would kindle the interest of kids in trying out the reaction of different substances in various solvents.

The Mr.G Show presents how to make "hot ice" more commonly known as sodium acetate in the kitchen. You start with one liter of white vinegar which you place into a sauce pan. You add four table spoons of baking soda to the pan being very careful because both chemical together will react an may cause a big mess so be prepared to clean up any boil over that may arise. Wait while this mixture boils down for the real fun to starts. The hot ice created will transform from a liquid to a solid before...

Inside the container we have some water molecules and inside those water molecules we have some sugar molecules. We have more water molecules so in this case the thing which is more of called SOLVENT and the thing which is lesser is called SOLUTE. We can say sugar molecule dissolves in the water. The combination of Solvent and Solute is called the SOLUTION. Diffusion is spreading the molecules from high concentration to low concentration. If we take two containers of water which are joined from...

This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many...

From The Apprentice Doctor, a video regarding "Cavernous Sinus Thrombosis", which means a blood clot in the cavernous sinus. The cavernous sinus is in the base of the brain and contains several nerves, a vein and many other structures. The vein that sits in the Cavernous sinus carries deoxygenated blood from the brain & face and brings it back to the heart. This video shows how to spot Cavernous Sinus Thrombosis in a patient's protruding eyes.
